Sanguirana luzonensis, also known as the Luzon frog, is a species of true frog, family Ranidae. It is endemic to the island of Luzon (including some associated islands), the Philippines. It occurs in swift-flowing, cool mountain streams and rivers in montane rainforest at elevations up to 2000m (7,000feet). It is very common in many habitats, although it is suspected to be declining because of habitat loss and deterioration.
